A floor plan concept for an easily convertible detached house

After seeing many posts in here regarding conversions and aging-in-place, I wanted to just for fun try my hand at designing an affordable but flexible house that would bend to life's needs with minimal need for more costly work. I was inspired by Finnish "type houses", which were after-war standard houses built for veterans and for the global market. They are still very loved after 60 years, but are often on the smaller side which means they mainly work for single-family living. Modern ideas of good life also nowadays means a room for every child and maybe a chance to live close to but not with one's aging parents. And the original type houses were not built with today's accessibility needs and standards in mind.

So, I tried to scale up the original plans a bit, making equal rooms that can be used for many purposes. One of the "quadrants" of the house is dedicated to the stairs and utilities. The rooms don't have much built-in storage as I found that made them a bit less flexible, but I'd love to hear your thoughts on that too!

I designed this with Finnish (accessibility) needs in mind, so there is a free space with a diameter of 1300mm shown in critical spots. The doors are primarily 900mm wide excluding a couple storage room doors, the sauna door and the smallest WC door. And a sauna is a necessity in a house like this, but I tried to locate it so that even if the house is used by multiple resident groups, they all would have access to the same one.

I tried to keep affordability in mind by challenging myself to keep it under 150 m^2 . I did find adding another 600mm to the width of the house made a difference in the comfort of a couple spaces, but that sadly put me a bit over my initial goal (The alternative layout is 156 m^2 while the main one is 145 m^2 ). I also tried to make walls be as as straight and clean as possible, but there are a couple places I'm still a bit unsatisfied with especially in the stair/utility corner. There are also two quite roomy chimneys or ducts on different sides of the house to make plumbing changes easier.

But yeah, I probably just wanted to share my thought and would love to hear your thoughts on what makes a floor plan "timeless" and functional even years from now. Or if you see places for improvement, that'd be awesome too! I'll try to post a floor plan of the original "type houses" in the comments, I have bad experiences with the quality of pictures lowering when trying to post multiple at once.
